Binding-site concentration and conditional stability constants for copper and fish gill surface interactions were calculated based on the data from the literature. Six scenarios were modeled by including or excluding pH and alkalinity differences between the fish gill microenvironment and the bulk solution and the presence of free mucus in the calculation. We demonstrate that changes in pH or a...

Eurihaline fish support waters with different salt concentration. However, numerous studies have shown that salinity can affect fish development. Thus, the effect of salinity change from 20 to 5 and 35 on survival, weight, length, gill chloride cell ultrastructure and gill Na+, K+ ATPase activity was evaluated in Centropomus parallelus following short-term (6, 24 and 96 hours) and long-term exp...

Potomida semirugata, which belongs to the Unionidae family, require a host fish complete their life cycle. In this study, preference of species was investigated. Besides, mussel and hence attachment state larvae on were also Five different namely Cyprinus carpio, Oreochromis niloticus, Clarias gariepinus, Anguilla anguilla, Carasobarbus luteus used as candidates. five glass aquaria each contain...

in order to evaluate the competitive ability of legume cover crops on interference of weeds in corn, an experiment was carried out in sari agricultural sciences and natural resources university during 2011 growing season. this research was carried out based on complete block design with three replications. treatments consisted of three cover crops including: soybean (glycine max l.), fenugreek ...

PURPOSE The aim of this study was to estimate the mechanical properties (elasticity) of normal and cancer prostate tissues and to develop a tissue elasticity map for the diagnosis and localization of prostate cancer. MATERIALS AND METHODS A total of 735 sites from 35 radical prostatectomy specimens were used in the experiments using a robotic palpation system, and the elasticities of the spec...

A total of 1,830 specimens (75.7% respiratory and 24.3% nonrespiratory) were cultured in parallel with the MB/BacT and BACTEC 460 TB systems and on Lowenstein-Jensen (LJ) medium. Mycobacteria were identified from 173 (6.5%) specimens. The most common species recovered were Mycobacterium tuberculosis complex (65. 9%), Mycobacterium avium complex (22.5%), and Mycobacterium chelonae (9.2%). The re...

Taurine, a principal osmolyte in molluscan integument, is actively transported from sea water by Mytilus gill by means of a Na(+)-dependent process. In this study we examined the response of this transport to reductions in external salinity, i.e. the response to reductions in osmotic concentration as well as Na+ concentration. Acute exposure of isolated gill tissue to 60% artificial sea water (...

Sampling was done using 90 post larvae which were produced by reproduction of some broodstocks of Fenneropenaeus indicus in one day and reared in the same situation for 4 months. Samples were divided into 3 groups: high, medium and low growth (based on weight and length). Genomic DNA was extracted from muscle tissue using the phenol-chloroform method. The polymerase chain reaction (PCR) was car...
